Why bacillus cereus more heat resistant than aspergillus Niger?

∙ 12y ago
Even though they both contained spores, I believe the reason why A. Niger is less heat resistant is because it is a fungus and in the domain eukaryota. Therefore, it needs a level of humidity in the air to produce molds; an ability of most members of the fungi species. B cereus is a facultative anaerobe, and its bacterial growth generally occurs around 10-50 degrees celsius. While, a. Niger maximum temperature is around 40 degrees celsius.

Bacillus cereus is more heat resistant than Aspergillus Niger due to its ability to form endospores that help protect it from extreme conditions, including heat. These endospores act as a protective structure that allows the bacterium to survive in harsh environments. Aspergillus niger, on the other hand, does not form endospores and therefore is not as heat resistant.

Where is glucoamylase produced?
Glucoamylase is produced by various microorganisms, including fungi such as Aspergillus niger and Rhizopus species, as well as some bacteria like Bacillus species. It is also found in small amounts in human saliva.
What is the meaning of isolation of aspergillus Niger?
Isolation of Aspergillus niger refers to the process of separating and identifying this particular species of fungus from a sample or environment. This can involve techniques such as culturing on specific growth media, microscopy, and biochemical tests to confirm its presence and characteristics. Aspergillus niger is a common mold known for its ability to produce enzymes and organic acids.
What are the carbon sources of aspergillus Niger?
Aspergillus niger can utilize various carbon sources including glucose, fructose, sucrose, and starch. It is known for its ability to efficiently metabolize and utilize a wide range of carbon compounds for growth and metabolism.
What are pancreatic amylase secreted by?
Pancreatic amylase is secreted by the pancreas. It is an enzyme that helps in the breakdown of carbohydrates into smaller sugars such as maltose and glucose to facilitate their absorption in the small intestine.
Where is the source of the Niger river?
The source of the Niger River is in the Fouta Djallon highlands in Guinea, where it starts as a small stream before flowing through several countries in West Africa.
Why is B Cerus more heat resistant than A Niger?
B. cereus is a spore former. Spores are known for their very high heat resistant qualities.
What is the pathogen of aspesgillosis?

Three different types of fungi and what they do?
BRACKET FUNGI:-Bracket fungi are commonly found growing on trees or fallen logs in damp woodlands. They can severely damage cut lumber and stands of timber.PENICILLIUM:-Common on foodstuffs, leather, and fabrics, they are economically important in producing antibiotics organic acids, and cheeses such as English Stilton, Italian Gorgonzola, and French Roquefort.ASPERGILLUS:-Aspergillus niger causes black mold on some foods; Aspergillus niger, Aspergillus flavus, and Aspergillus fumigatus cause aspergillosis in humans. Aspergillus oryzae is used to ferment sake, and Aspergillus wentii to process soybeans.
